Interview Questions: Analysis of Algorithms

3-SUM in quadratic time. Design an algorithm for the 3-SUM problem that takes time proportional to n2 in the worst case. You may assume that you can sort the n integers in time proportional to n2 or better.

Note: these interview questions are ungraded and purely for your own enrichment. To get a hint, submit a solution.

Hint: given an integer x and a sorted array a[] of n distinct integers, design a linear-time algorithm to determine if there exists two distinct indices i and j such that a[i]+a[j]==x.

      Golang的包管理有两个特点，一个是去中心化，也就是说，不像Node.js有一个npm，包的仓库可以是任意的代码仓库。一个是代码仓库跟代码本身耦合在一起（比如导入一个包是 "github.com/langresser/websocket"），这个是Golang推荐的工作方式。

      好处是go get命令可以轻易的安装好一个项目的依赖（自动从github上面clone，并放在GOPATH的第一个路径中），坏处是不能进行版本控制，一旦情况复杂起来就力不从心（比如某个第三方库的接口有修改，可能导致A的电脑上能正常运行的，B使用go get执行完反而不能正常运行）。

     下面是我总结的一些工程管理经验。



1、建立一个golang文件夹，里面包含两个会加入到GOPATH中的文件夹：

KVM OSX Guest 10.11 (El Capitan) with Clover

• Some notes about this approach:
  • An OSX Installer USB drive for Install OS X El Capitan is created
  • Clover is then installed on the USB drive
  • Clover Configurator is then run on the USB drive
  • The USB drive contents are copied to the VM host
  • VNC is used to connect to the guest UI
• The qxl virtual video device is used (part of the standard kvm qemu install)

Building OpenSSL 1.1.0 with Microsoft VS 2015

MCCI needs OpenSSL for a Windows project (that will be cross-platform). A casual search didn't turn up either a good source for cross-platform libraries, which meant we have to build them ourselves. A deeper search found a detailed guide here, and yet the details don't match what I found when I checked out the code; and the post doesn't talk about doing it directly from GitHub (which I wanted to do).

Here's the procedure for building OpenSSL on 64-bit Windows 10, with Visual Studio 2015.

1. If you don't have it, please install git bash from git-scm.com.
2. Start a git bash window.

   In the following, I'll use lines beginning with {dir} $ to designate input to a bash Window. We'll also have to use a cmd.exe Window for much of the build, and those lines will be marked {dir}>, just as on Windows..
